To all eli/tom it may concern:

Be it known that T, STEPHEN J. CLULEE, a citizen 0f the United States, and a resident of Attleboro,v in the county of `Bristol and State of Massachusetts, have invented an Improvement inEyeglasses, ofv which the following is a specification. y

This invention relates to eyeglasses. One of the objects thereof is to providea simple and practical construction for eyeglasses of highly eiicient and dependable action. Another object is to provide a'construction which shall be durable and in which the metal is economically used. Another object is to provide a fconstructionrof the above type in which the parts are securely interlocked and yet `readily assembled or taken apart. Other Objects Willlbein part obvious and inpart pointed Outhereinafter.

`The invention accordingly'eonsists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified ,in the construction here# inafter described, and the scope' of the a`ppli-"` CatOn 0f which will be indicated in the fol lowing claims. i 1

In the accompanying drawing-7 in`which is shown one or more of various possible em-l bodiments of several features of this invention, o i

Figure 1 is a rear view of mounting and associated parts; o o

Fig. 2 is a top plan of the parts shown inFigzl;

Fig. 4 isa bottom of Fig. 1; d Fig. 5y is a detailed `rear elevationof a p0rtion of another form of eyeglasses;

Fig. 6 is a top `plan view of thehparts shown 4in Fig. 5;

Fig. 7 is a detailedsectional elevation talen` on the line 7=-7 of Fig. 6" and showing the parts on a larger scale. y

Similar reference characters refer to similar parts throughout the several features of the drawing. 1

Referring' now t0 Fig. 1of the drawings there is shown an eyeglass lens "10, but it may here be noted that the term eyeglasses is used throughout in a broad sense to denote any device for supporting a lens for theeye. The lens 410l is embraced in a lenselamp threaded for the a `guard arm plan view of a portion 11` of the ordinary form comprising the' l strap 12 and side lugs 13 secured one 'to' anf the screw '14 `passing' through the stood that the parts at the opposite' side of i the bridge. are substantially identical with those-herein described and these parts are* not shown in duplicate or separably def scribed herein.,v as it is desired to avoid en-` eumbering this description in the accompanying drawing. y

Passing through the part 15 and preferably rigidly secured therein is a sleeve 17 which extends materially above and below the former part. This sleeve is internally purpose hereinafter described and is provided at lits lower end with a Harige 18` and slot 19.

`Mounted upon the field part 15 as a sup port is a swinging guard arm or lever 20 having jointedto its inner end a nose pad or guardl.` The outer end of this guard arm isformed into aV fingerpiece 22 by" whichthe parts are swung into the position indicated at dotted lines at23`in Fig. 2 of the drawings, as for the purpose `of placing the eyeglasses upon the face or removing them therefrom. This guard arm, which is broken away in Fig. l of the drawings to show the construction more clearly, is piv` otally mounted about the upper end of the sleeve 17. The opening 24 in the guard arm which may be assumed t0 be of the gold-A a small perforation and thereafter forcing -the metal away fromthe plane 0f the body portion of the arm. Bv this action there is formed a flange 25 which, even with the` gold-filled constitution of the guard 'arm offers gold as a bearing metal upon allfof` its surfaces. This, arrangement is highly ad! vantageous as the t`old forms afar better bearing metal than the base metal which itI incloses and is also less subject to corrosion. The inner gold surfaces of the guard arm at 26 fit snugly the outercylindrical surface of the sleeve 17 and provide a tubular bearing of considerable length, thus `permitting for a given stability of the bearing a smaller engaging surface at 27 between thebottom` of the i guard arm and the top of the "field portion 15. Furthermore,` the upright flange incassa to the plane of thev glasses, a lever provided with an opening fitted about said bearing and having an annular flange about said opening,

and a screw entering said tubular member and engaging said lever to hold it in position, the head of said screw brace said flange and extending downwardly to bear against the body of saidlever.

5. In eyeglass construction, in combination, a bridge portion, a supporting portion adjacent the end of said bridge portion, a lever provided with an opening with anannular flange about said opening and securing means against which said opening and flange forma bearing and provided with a head resting against the upper surface of said flange, said head having an annularlre`` cess within which said flange fits. n

6. In eyeglass construction, in combina tion, a lens clamp, a bridge, bearingmeans interposed between said lens clamp and said bridge, a perforated guard arm having an annular shoulder or ange extending about its perforation and in the direction thereof, Said guard arm being pivotally mounted upon said bearing means with its upper and lower surfaces and the outer surface of said extension in contact 'with and bearing against said bearing means, and a spring tending to swing said guard arm in a predetermined direction.

7. In eyeglass construction, in combina- 9. In eyeglass,` construction, in combinar` tion, a" lens clainp, aibridge,

being shaped to ein-` said the gold extending `porting portions, n vided with an opening surrounded by `an supporting` supporting means interposed between said lens claiiip `and said bridge, a sleeve passing through said supporting means,` a guard arm provided with a perforation, and an annular flange by which said perforation is extended,

said guard arm being fitted about said sleeve, i

a screw threaded iito the inner surface of n said sleeve and provided with a depending flange on its head embracing the annular ex tension of said guard arm and a spring tending to swing said guardarci.;

tion, a lens clamp, a bridge, supporting means interposed between said lens clam `and said bridge, a sleeve passing tlirougi said -supporting nieans, a guard arm provided with a perforation `and an annular flange by which said perforation is extendl0. In eyeglass construction, in combina i ed, said guard arm being fitted about said i sleeve, a screw threaded into the inner sur face of said sleeve and provided with a depending ange on its head embracing the annular extension of said guard arin, a spring tending to swing said guard arm,

struction and having said annular extension forced upwardly froinits body portion with over substantially its er1- tire bearing surface.

1l. .In eyeglass construction, in combination, a bridge, a supporting portion at each endof said bridge, an annular bearing part extending upwardly from each of said supa pair of levers, each proannular flange, said openings and flanges respectively fitting and bearing on said an` nular portions and a pair of screws respectively threaded downwardly through said annular portions and provided with heads having annular recesses embracing said tubular portions and said anges.

In testimony whereof I have signed my naine to this specification this ninth dayof August, 191e.
